Apple will release three upgraded iPhones by the end of the year — despite launching its latest model just four months ago — tech analysts and Chinese newspapers report.

Two of the new models — the iPhone 5S and a first-of-its-kind low-budget iPhone — are due out by June, according to the China Times.

The third device, a larger-screened iPhone 6 with a 12-pixel camera, could be available by Christmas, analysts say.

The business move may be coming because Apple is feeling demand from folks who can’t afford smartphones, Wall Street tech market analyst Peter Misek told The Post. He also said the Samsung-style look of a big screen is gaining popularity. “A large percent of the population wants bigger screens — so there’s a demand for that and it’s hurting them,” Misek said.

Misek — who correctly predicted past iPhone features— said he is “confident” that the iPhone 5s will have an 8-megapixel camera and will hit shops by June. He also said the company’s “affordable” $250 iPhone will be heavier and made of polycarbonate material. The iPhone 6 will likely feature a 4.8 inch screen, he said.

The move is unusual for Apple, which has in the past released only one iPhone per year.

Natalie Harrison, a spokeswoman for Apple, refused to offer details about any in-the-works products.
